A few weeks ago I reinstalled Windows 10 and since then it has been having ridiculous performance that I tried to ignore but I can't anymore. It's lag like when your CPU is overloaded an everything starts running ShowboxTutuappVidmate horribly, except that's not what's happening. I could have nothing more than google chrome with 2 tabs open and suddenly the performance will be horrible, video is laggy, mouse is laggy, etc. and then it's normal for a while until another spike and repeat. This never happened before I had reinstalled Windows 10 a few weeks ago.
